INTERNAL-COMBUSTION ENGINE.

Application filed July 17,

To all whom it may concern Be it known that 1 SAMUEL B. (ion), a citizen of the United States,-residing at In dependence, in the county off-Jackson and State of Missouri, have invented-certain new and useful Improvements in InternaLUombustion Engines, of which the following is a specification.

Th'isinvention relates to internal coinbustion engines and my object is to produce a construction whereby such engines can be operated efiiciently and reliably with crude oil or other liquid hydrocarbon fuel of low specific gravity. More specifically my oh joct is to produce a construction for causing the hot blasts of the exhaust gases to ill]- pinge upon and substantially envelop the casing of the throttle valve of the engine, for the purpose of highly heating said cas ing and valve and thereby effecting the superheating of combustible gases just prior to the entrance thereof into the compression chamber of the cylinder of the engine. A further object is to produce a construction of the character mentioned, which is simple, strong, durable and inexpensive.

\Vith the objects named in view the in vention consists in certain novel and peculiar features of construction and organization of parts as hereinafter described and claimed; and in order that it may be more fully understood reference is to be had to the ac companying drawing, in which:-

Figure 1, is a fragmentary front view of an internal combustion engine embodying my invention.

Fig. 2, is a horizontal section taken on the line II--II of Fig. 1.

Fig. 3, is a vertical cross section taken on the line IIIIII of Fig. 1.

Referring to the drawing in detail, 1 indicates the head end of the cylinder of an internal combustion engine of any suitable type, 2 is the pipe-Way for supplying a com bustible mixture to the compression chamber, not shown, of the engine, and mounted upon said pipe adjacent the head of the engine is a casing 3 containing a throttle valve 4, the valve bein shown as of the butterfly t pe, though it will be understood of course, t at the special type of valve is unimportant. It will be noticed that the lower member of the pipe-way 2 communicates with the valve chamber at the lower side of the same and that the upper member of the Specification of Letters Patent.

1916. Serial No. 109,815.

said pipe-way leads from the upper part otthe said chamber to the cylinder at the point where it is controlled by the customary or any preferred type of intake valve, not shown.

The valve casing is preferably formed integrally with a ol-low housing 5, whose front, top and bottom walls preferably comcide in position with the corresponding walls of the valve casing.

The housing 5 is of length and form to provide a passage (3 extending from a point at one side of the valve casing to a point at the opposite side thereof, the llilvl'lih diatior throat portion of said passage Iy ing back of said casing, so that hot from the exhaust port of the engine, passing through the pipe-way T, and entering the housing at one side thereof, shall inipinge upon the adjacent side wall of the valve casing and then pass along the rear thereof to the opposite side of the said housing, at which point the gases escape through a pipe 8 to the atmosphere, or to a miifiier, not shown, of any suitable or preferred type. It will thus be seen that the hot exhaust gases are applied in successive blasts dircctly upon one of the side walls of the casing and that such hot gases before escap ing also come in contact with the back wall and the other side wall of said casing, and that such extended or enveloping contact results in raising the valve casing and the valve therein to a temperature which effects the superheating of the combustible mixture passing through the valve chamber to the cylinder and effectively guards against any congealing of such mixture in said chamber. Because of this a combustible mixture, of which vaporized crude oil or equivalent hydrocarbons is a constituent, can be effectively employed for the operation of an in ternal combustion engine, the special type of carburetor or other vaporizing device, not shown, being unimportant.

To avoid such rebound of the hot gases from the wall of the casing upon which they impinge as would unduly retard the circulation of such gases, said wall is sloped rearwardly as at 9, and the rear corner 10 of the casing is rounded at the entrance end of the throat or intermediate portion of the passage of the housing.

From the above description it will be apparent that I have produced means for of g'ascs Patented Aug. 24, 1920.

iicienily superheating the combustible mi);- ture for an internal combustion engine, as it passes the throttle valve, which will be found oi advantage in the operation of internal combustion engines; with liquid fuel of any specific gravity, and While I have illustrated and described. the preferred cinhoiliinent of the invention, it is to be unalci'slood that I reserve the right to make all changes in the fUl'lll, proportion, and arrangement 01 parts \vhicleproperly fall within the spirit and scope of the append ed claim.

I claim:

In an internal combustion. engine the coinhination oi a cylinder, a housing" underlying, and extending transversely of the cylinder and. provided at one end with a gas receiv ing and at the other end with a gas discharging: opening, an exhaust gas pipe connecting the cylinder with the receiving opening of the housing and a discharge exhaust gas pipe connected with the other end oi the housing; said housing having a front will substantially straight and substantially in line with said openings and a haul; wall. bowed rearwardly from and between said openin the front wall having a portion projecting rearwardly into the housing to eonstriot the central portion of the passage thereof and intercept the direet path of travel oi the exhaust gases from the exhaust gas supply pipe and defieet them rearwardly through said constricted throat of the passage, said rearwardl v projecting portion having a horizontal. cylindrical opening extending from front (to rear to give aoeess to the valve chamber, a removable plug closing the last nan'iedopehing, and forming a journal ifor the valve, and vaporizing fuel supply and discharge pipes tfUllTlnlUIllCflblH'g with said receiving and :discharging: openings.

in testimony whereof I afiix my signature,

in the presence of two Witnesses.
